Thanks guys, really appreciate it.It will save me a lot of testing, I can only shoot when weekends,I'm new shooting RAW, I am still getting used to on my workflow.These inputs will save me precious time and precious pictures.

Additional quick question: What aperture you normally use? when you dont intend bokeh.

Again, I am used to with my G12, I always shoot at maximum at 2.8. So when I got the 6D, its 2nd nature to me to shoot < 2.8.

your comparison of apertures between the g12 and the 6D will be problematic. you are dealing with a lot less depth of field on your 6D.

for max apertures i will only go to 2.8 or wider if i am dealing with a single subject and it depends greatly on the lens. on the 35L i am comfortable with the IQ down to F2.0...on my 70-200 2.8L i feel better at F4 but will go to F2.8 with the understanding that i will probably be getting soft results on a percentage of shots.

for group small shots (2 to 3 people) i dont feel comfortable going wider than F5.6 but i will sometimes fudge it at F4 if i am desperate for light. for corporate head shots i try not to go wider than F8. for creative head shots i'll go to an F2 if i can.

for sports i tried to stay at 5.6 or smaller as i wanted greater depth of field to compensate for the players movement throughout the frame. if i tried to shoot at F2.8 often times the players had moved out of my depth of field in the fraction of a second that it took the camera to focus and release the shutter. this was on the 5D series cameras which of course were less than ideal for action in terms of that focusing system.

its all highly dependent upon then lens (focal length) that i am using and what the situation calls for. the full frame format is an entirely different animal in terms of Depth of Field and you should not reference your experiences on your G12 as to what apertures will work in certain situations.

My experience with the 5d iii is that i cannot go above 3200 without losing significant sharpness. Interestingly I was shooting at a high school basketball game with a guy using a nikon D4 and the pics were tack sharp at iso 8000. Will the 1dX tolerate this high of ISO? This is an honest question not a nikon vs canon comment.

1D-X does better than that. It is unbelievable the shots they are able to pull out of that sensor.

eninja, what lens/lenses are you shooting with on the 6D? Your questions would be better answered specifically referring to your actual equipment rather than general settings from random body and lens types.
